Don`t worry. I`ve erected many rhombics. They were all astisfactory and
very forgiving. Most were about 4 or 5 wavelengths on a side (leg) and
they were about twice as long as wide. They all worked well over a wide
range of frequencies. It`s just a terminated transmission line with a
big spread in the middle so it will radiate. Matching is a cinch.
